Abstract

1,103,050. Key for musical instrument. PRATT, READ & CO. Inc. 12 Aug., 1965 [4 Sept., 1964], No. 34554/65. Heading G5J. [Also in Division B5] A key for a keyboard instrument is made by forcing a moulded plastics cap 14 against and downwards on to glued shank 13, where it rests on shoulders 31. To ensure a neat finish, and to enable easy release of the cap from the split mould cavity in which it is produced, the mould is divided at about 45 degrees to the horizontal, as shown by the parting line 61. The natural piano key shown is provided with a sideways extension 25, so as to fit around the adjacent sharp key. Extension 25 does not rest on shank 13, and is supported by it only indirectly. Methods of capping sharp keys and of cutting key shanks and keyboards prior to capping are also described. Similar keys and keyboards may be employed in instruments other than pianos, such as organs, harpsichords &c.
